Definitions

  • the present invention is directed to containers that can be used to separately store two substances and to mix the substances as needed. More specifically, the present invention is directed to a baby bottle for storing water and powdered formula separately until they need to be mixed to feed a baby.
  • Baby formula is typically prepared by mixing a measured amount of powdered formula with a measured amount of water. This mixing must be done just prior to feeding the formula to the baby; otherwise, the formula will spoil. This presents a problem when parents are traveling and do not have a convenient way to store the water and formula separately.
  • Bottle designs that address this problem, having dual chambers and mixing systems, are known in the art. But the prior-art mixing systems often involve complex mechanical devices or specialized bottles that are expensive to manufacture and that must be cleaned and stored. In addition, prior-art designs may require special tools that must be used in conjunction with the bottle.
  • the invention includes a container having a first compartment configured to hold a first substance, a second compartment configured to hold a second substance, a frangible separator coupled to both the first and second compartments, and an actuator operably attached to the frangible separator.
  • the second compartment is removably attached to the first compartment.
  • the frangible separator forms a seal between the first compartment and the second compartment such that the first substance and the second substance do not mix. Actuating the actuator causes at least a portion of the frangible separator to rupture, which creates an opening in the frangible separator and allows the first substance and the second substance to mix together.
  • the invention also includes a bottle for storing and mixing liquid and powder.
  • the bottle includes a first compartment assembly configured to store a liquid; a second compartment assembly removably attached to the first compartment assembly and being configured to store a powder; a frangible separator coupled to both the first compartment and the second compartment and forming a seal between the first compartment and the second compartment such that the liquid and the powder do not mix; and an actuator string operably attached to a central frangible portion of the frangible separator.
  • a first end of the actuator string is attached to the central frangible portion, and a second end of the actuator string extends to through the wall of the bottle to the exterior of the bottle, such that pulling the actuator string in a direction away from the bottle causes the central frangible portion to rip, thus creating an opening in the frangible separator and allowing the liquid and powder to be mixed.
  • the invention also includes a frangible separator having a separator body and an actuator string partially embedded within the separator body and partially extending outward from the separator body.
  • the actuator string is configured to partially rupture the separator body when the actuator string is pulled.
  • FIG. 1 is a perspective view of an embodiment of the invention, showing a bottle having a liquid compartment assembly, a powder compartment assembly, and a nipple assembly;
  • FIG. 2 is a side elevation view of the bottle shown in FIG. 1 ;
  • FIG. 3 is a cross-sectional view of the bottle of FIG. 2 taken along line A-A;
  • FIG. 4 is a detailed cross-sectional view of area B shown in FIG. 3 ;
  • FIG. 5 is a detailed cross-sectional view of area C shown in FIG. 4 ;
  • FIG. 6 is a top perspective view of an embodiment of a frangible separator for separating two compartments, according to an embodiment of the present invention.
  • the container of the present invention facilitates storage of two substances in two distinct compartments to prevent mixing of the substances until a user actuates a mechanism to at least partially remove a separator between the compartments.
  • a container with a frangible separator according to the present invention may be used to store any type of material, but is particularly well suited for storing materials separately and mixing the materials when needed.
  • the materials to be stored an mixed may be any combination of liquids, solids, and gases.
  • a container according to the present invention may include any number of compartments, with a frangible separator between each of the compartments.
  • the container includes functionality for both separately storing two substances and for mixing the two substances when desired.
  • FIG. 1 an exemplary embodiment of the container is shown in FIG. 1 .
  • the container is a bottle designated generally by reference numeral 100 .
  • FIG. 1 shows a perspective view of bottle 100 , which includes three sections: a liquid compartment assembly 102 , a powder compartment assembly 104 , and a nipple assembly 106 .
  • FIG. 2 is a side view of bottle 100 ;
  • FIG. 3 is a cross-sectional view of bottle 100 taken along the line A-A in FIG. 2 .
  • nipple assembly 106 may include internal threads configured to mate with upper exterior threads 108 on a top exterior surface of liquid compartment assembly 104 to removably secure the nipple assembly to the bottle.
  • Liquid compartment assembly 104 may also include lower exterior threads 110 on a lower exterior surface of the liquid compartment to removably secure powder compartment assembly 104 to liquid compartment assembly 102 .
  • Powder compartment assembly 104 may be removably secured to liquid compartment assembly 102 in any suitable manner, including a press fit or a snap fit.
  • the exemplary embodiment shown in the figures shows liquid compartment assembly 102 and powder compartment assembly 104 as being removably attached to one another, liquid compartment assembly 102 and powder compartment assembly 104 may also be integrally formed as a single, unitary body.
  • separator 112 divides a liquid compartment 114 within liquid compartment assembly 102 and a powder compartment 116 within powder compartment assembly 104 such that liquid held within liquid compartment 114 cannot mix with powder held within powder compartment 116 .
  • separator 112 is a frangible separator having an actuator 118 configured to rip or rupture a portion of the frangible separator 112 and thus allow the liquid held in compartment 114 to mix with the powder held in compartment 116 .
  • Actuator 118 may be a string, a rod, or a lever, or any other suitable actuating mechanism.
  • actuator 118 is a string attached to frangible separator 112 and extending out to the exterior of bottle 100 such that when the string is pulled, the separator is ruptured and the liquid in chamber 114 and powder in chamber 116 can mix together.
  • FIG. 4 shows a detailed cross-sectional view of frangible separator 112 and actuator string 118 .
  • actuator string 118 is embedded within frangible separator 112 and extends to a central portion 120 of separator 112 .
  • actuator string 118 is pulled in a direction perpendicular to the longitudinal axis 122 (shown in FIG. 3 ) of bottle 100 —represented by arrow 124 in FIGS.
  • actuator string 118 rips a portion of frangible separator 112 to create an opening in frangible separator 112 and thus allowing the liquid and powder in compartments 114 and 116 to freely mix.
  • Actuator string 118 may included a pull tab 128 attached to the end of the actuator string to assist a user in gripping the string and pulling it in direction 124 to rip frangible separator 112 .
  • frangible separator is permanently attached to powder compartment assembly 104 by an adhesive or other suitable means.
  • This embodiment allows manufacturers of baby formula, for example, to sell pre-measured amounts of formula sealed within a powder compartment assembly 104 that is configured to be removably attached to liquid compartment assembly 102 .
  • This embodiment allows consumers to quickly assembly a ready-for-use baby bottle by simply attaching the pre-packaged powder compartment assembly and filling the liquid compartment assembly with water. This avoids any need to measure formula.
  • frangible separator 112 is a disposable separator, not permanently attached to powder compartment assembly 104 .
  • separator 112 may rest on a lip 126 of powder compartment assembly 104 and be firmly secured between lip 126 and the walls of liquid compartment assembly 104 when the two compartment assemblies are removably coupled to one another.
  • a washer or other seal may be used to facilitate the coupling.
  • Using an independent frangible separator 118 allows both compartment assemblies 102 and 104 to be reused by simply uncoupling the compartment assemblies, filling powder compartment assembly 104 with formula, inserting a new disposable separator 112 , filling the liquid compartment assembly 102 with water, and attaching a lid or nipple assembly 106 to bottle 100 .
  • FIG. 5 is a detailed cross-sectional view of the interface between liquid compartment assembly 102 , powder compartment assembly 104 , and frangible separator 112 . As shown in
  • powder component assembly 104 includes a slot 130 that extends through the sidewall 132 of powder apartment assembly 104 .
  • Slot 130 is configured to allow actuator string 118 to extend outward to an exterior of bottle 100 , such that tab 128 can be easily gripped and pulled by a user to rip frangible separator 112 and mix the substances within liquid compartment 114 and powder compartment 116 .
  • separator 112 creates a seal between liquid compartment assembly 102 and powder compartment assembly 104 such that no liquid held in compartment 114 will leak into powder compartment 116 .
  • separator 112 seals off slot 130 such that no liquid or powder will leak from bottle 100 through slot 130 .
  • actuator string 118 remains embedded within separator 112 , and the edges of separator 112 remain intact, thus preventing any leakage of liquid after separator 112 has been ruptured.
  • FIG. 6 is a top perspective view of the frangible separator 112 .
  • separator 112 may include a separator body 134 having a central frangible portion 136 .
  • Separator body 134 may be of any suitable shape and size, provided that it can sealingly divide liquid compartment 114 and powder compartment 116 .
  • central frangible portion 136 is attached to a first end of actuator string 118 , with the second end of actuator string 118 extending outward from separator body 134 .
  • Central frangible portion 136 may be of any suitable shape and size.
  • FIG. 6 shows a frangible portion 136 having a horseshoe shape—that is, a shape with a flat portion 138 configured to be near sidewall 132 of powder compartment assembly 104 while in use and a curvilinear portion 140 that extends outward from flat portion 138 toward central portion 120 of the separator 112 and back to flat portion 138 .
  • frangible portion 136 may be semicircular in shape.
  • Actuator string 118 may be attached to the borders of frangible portion 136 such that when actuator string 118 is pulled away from bottle 100 in direction 124 , the borders of frangible portion 136 are ripped, thus creating an opening between liquid compartment 114 and powder compartment 116 .
  • frangible portion 136 may include weakened areas along its border, with actuator string 118 attached to a central location within frangible portion 136 . In this embodiment, pulling actuator string 118 will put stress on the weakened areas, causing the weakened areas to rupture and allowing the substances in compartments 114 and 116 to mix.
  • Frangible separator 112 may be made from any suitable material. Because the process of ripping or rupturing separator 112 cannot be reversed, the separator may be made from materials that are inexpensive and easily disposable or recyclable.
  • bottle 100 greatly simplifies the storage and mixing of baby formula with water and allows parents to very quickly and easily put together a baby bottle that can be carried securely and mixed on demand.
  • the bottle can be prepared in a few easy steps: first, powder compartment 116 is filled with a pre-determined amount of infant formula.
  • powder compartment assembly 104 includes gradations or other indications on the its interior sidewalls to aid a parent in determining the correct amount of formula to add.
  • frangible separator 112 is placed on lip 126 of powder compartment assembly 104 , with actuator string 118 extending outward through slot 130 .
  • liquid compartment assembly 102 is coupled to powder compartment assembly 104 , and in the process, frangible separator 112 is sealingly secured between the two compartments.
  • frangible separator 112 is sealingly secured between the two compartments.
  • a predetermined amount of water or other liquid is added to liquid compartment 114 .
  • the liquid compartment assembly may also include gradations or other indicators to assist the parent in determining the appropriate amount of water to add.
  • nipple assembly 106 is secured to a top portion of liquid compartment assembly, and the bottle is ready to go. When it is time to feed the baby, the parent simply has to pull actuator string 118 in a direction 124 away from bottle 100 to create an opening in frangible separator 112 , thus allowing the water and formula to be mixed. If necessary, the parent may shake the bottle to further facilitate thorough mixing.
  • the present invention provides for a container for with multiple compartments divided by a frangible separator.
  • the container allows a user to carry two substances, such as liquid and powder, in separate compartments and to quickly and easily mix the two substances when the need arises. Carrying the substances in separate compartments is essential for applications such as baby formula, which must be fed to the baby or refrigerated shortly after being mixed to prevent spoilage.
  • the present invention allows a parent to carry the formula in a ready-to-use bottle without the need for refrigeration or other special handling. It will be apparent to those skilled in the art that various modifications and variations can be made to the container of the present invention without departing from the scope of the invention as outlined in the appended claims and their equivalents.
